Abstract
This study was designed to examine the cost
effective feeding system of buffalo male calves for quality meat production.
Twelve buffalo male calves of 15-21 days of age and 41 ± 2 kg body weight (BW) were randomly divided into three
equal groups. Group A was fed milk replacer (MR)@ 8% of BW for the entire period of 90 days, group B was fed MR@ 4% of BW + early weaning diet (EWD) on
ad libitum and group C was fed MR@ 4% of BW + EWD for first 45 days and later on EWD only. Average weight
gain was 0.42, 0.46 and 0.52 Kg/d and dry matter intake was 0.65, 0.72 and 1.00
kg/d in groups A, B and C, respectively and the difference was significant
(P<0.01). Feed efficiency was superior (P<0.01) for group A (1.55) and B (1.62)
compared to C (1.94). Feed cost per kg weight gain of group C was 52 and 25%
less than calves in group A and B, respectively. In trial I (at 8th
week), digestibility of both DM and CP was higher (P<0.01) in group A (96.28 and
94.32%) than B (87.53 and 85.92%) and C (88.32 and 84.46%). Similar trend of DM
and CP digestibility was found in trial II (at 12th week). Dressing
percentage of group C was the highest (P<0.05), however, carcass
composition and weights of non-carcass components differed non significantly
among groups. Feeding calves MR @ 4% of BW + EWD on
ad libitum for first 45 days and later
on EWD was the most cost effective feeding system.
